Today's Lospec #pixel_dailies prompt was demon with a fun retro palette: https://lospec.com/palette-list/jr-comp -- I went to town on a mockup/redraw of a positively wild NES game called Zombie Nation. I'm not actually 100% sure the character you play as (a giant samurai head that spits fireballs) is actually a demon, but, idk, close enough.
I love everything about the way this game looks, even though I've never played it. It came up as I've been kind of studying NES sprites... and I'm so glad it did! Added the reference screen here in case you've never seen the beauty and majesty of this game, lol.
